To @ZZ whom it Duty concern,.-

Be it known that I, WILLIAM J. KENNY, of Chicago, in the county of `Cookand State of Illinois, have invented certain new and useful Improvementsin Machines for End-Seam,- ing Sheet-Metal Bodies; and I do herebydeclare that the following is a full, clear, and exact descriptionthereof, reference being had to the accompanying drawings, and to theletters of reference marked thereon, which form a part of thisspecification.

This invention relates to a novel machine employed in manufacturingcans, pails, or similar sheet-metal bodies.

The invention relates primarily to a novel device for uniting thebody-Wall with the bottom plate by means of a seam formed by folding themargin of the bottom plate over the margin of the body-wall.

The invention also embraces other improvements in machines of thischaracter, as will hereinafter more fully appear.

An organized machine in which my improvements are shown as embodiedembraces geuerally a suitable die-press, provided with averticallyreciprocating head, on which a forming-head is mounted, aplurality of dies for holding the sheet-metal body-blank and the bottomplate in position for being operated upon by said forming-head, andacarrier for said dies, by which they are successively brought intocooperation with the forminghead.

The invention consists in the matters hereinafter set forth, and moreparticularly pointed out in the appended claims.

In the drawings, Figure 1 is a side elevation of a press fitted withdevices embodying the principal features of my invention. Fig. 2 is aview, partially in section, taken on line 2 2 of Fig. 1. Fig. 3 isavertical central section, with parts broken away, taken through thepress, the forming-head, the die, and the die-carrier, showing thepositions of the parts when the press-head is at the uppermost part ofits stroke and showing a sheet-metal blankbody and a bottom blank placedon the die. Fig. 3 is a view in cross-section showing a detail of asleeve for raising the die on line 3 3 of Fig. Fig. i is a verticalcentral section through the forming-head, showing the side wings of theforming-head at their positions of initial engagement with the blank.Fig. 4t is a sectional detail of one of the side wings, together withits actuating-cam, illustrating the forming-jaw in its retractedposition, but before the wing has been retracted.

Referring in general terms to the machine illustrated, said machinecomprises a suitable die-press having the usual reciprocating head, acam-ring supported on the press, and a form- Fig. 7 is a similarverticaly IOO the head A.

ing-head mounted on the press-head and passing through the cam-ring ateach stroke of the press, so that its forming jaws or wings are broughtinto operative engagement with the cam-ring, dies suitable for carryingsheetmetal blanks, and a carrier ou which said dies are mounted so as tobe brought successively into position for engagement with theforming-head.

The machine is herein shown as adapted to be used in seaming oblongcan-bodies, such as used, for instance, for making sardine-cans; but itwill be understood that the machine may be adapted for operating uponsheetmetal bodies for other purposes and of other shapes than shown. Theterm can-blank. used hereinafter is employed merely for convenience ofdesignation.

In the drawings, A designates a die-press having the usual verticalreciprocating head A and a circular carrier-plate B, rotatively mountedon the lower portion ot' its frame. Saidcarrier is of the general formshown and described in my prior application for United States LettersPatent filed March 1S, 1901, Serial No. 51,587, and is not claimedherein. A cam-ring C is secured to the press below As herein shown,saidring is secured by means of projecting lugs c thereon to lugs a' on thevertical guides or column of the press, Fig. 2, so as to be in the pathof the stroke of the press-head. lts vertical poy sition relative to thepress-stroke is predetermined, the usual adjusting means of thepresshead being employed to obtain an accurate location thereof. Thepress-head A carries a forming-head D, having a plurality offorming-wings, hereinafter more speciiically described, adapted to bebrought into contact at certain portions of the stroke with camsurfacesformed on the cam-ring C, whereby lateral movement is imparted to thewings at the Vti me they are moved downwardly to bring said wings inposition with respect to the can B in such manner as to have limitedvertical oscillatory movement in conjunction with the press-head, eachbeing formed to carry a canblank.

Referring now especially to the formingheald D, said head comprises acentral head d, whose form is shown in Figs. 3, 4, 6, and 14. Said headis formed with an upwardlyprojecting stem d', adapted to engage avertical socket in the press-head A in the usual manner. Said stem d isprovided with a central vertical elongatedapertu re which forms a.pocket for a spiral spring F. The lower end of' saidv spring actsagainst a plunger f, which has limited vertical movement in the lowerand contracted part of said socket. .:lhe lower M end of said plungerprojects into a central opening d2 in the center lof the head d andcomes linto contact, ashereinafter more fully described, withwing-levers of the forming- ,head The upper 'end of the spring F comesinto operative contact, as shown herein, with a horizontal bar N. Saidbar N is secured transversely in the head A of the press in a suitableslot, so as to have a limited vertical movement, and is of sufficientlength to project beyond the sides of the head and come into engagementat or near the upper part of the stroke of the head with lugs or stopsal", which are secured to the main frame of the press. The spring F maybear against the press-head without the intel-position of the bar whenit is not desirable to compress the spring F at the latter part of theupstroke. The tension of the spring F is sufficient to hold the bar N atthe uppermost portion of its containing-slot when the bar N is not inengagement with its stops d10. Depending from said head d and pivotallysupported therein on trunnions are two sets of wings Gand G. .One set ofsaid wings G, hereinafter known as the side wings,7 are adapted toengage the middle portions of the sides of the can-blank between thecorners thereof, while the other set G are adapted to engage the sidesand ends of the blank, forming the corners thereof, and are hereinafterdesignated as the cornerwings. Vhen operating on cylindric cans, thewings corresponding to the corner-wings shown will have the form of arcsof a circle, and when operatin'gon otherforms of cans said wings will beVaried in shape to correspond to the particular shape of the can.Referring first to the side wings G, they each comprise a stem g, havingtrunnions g at its upper end, which engages trunnion-blocks g2, Fig. 14,so that the stem g swings in a vertical arc toward and from the centerof the head d.. Said trunnion-blocks g2 are secured to the head cl byscrews or other suitable means. Projecting outwardly from the upper endof the stern g is a horizontal arm g3. The outer end of the arm isprovided with an aperture Q12, which permits passage therethrough of aguide-pin c, secured in the cam-ring C, and the consequent engagement ofthe arm with a spiral spring cu in a manner hereinafter to be more fullydescribed. At the lower 'end of the stem g is secured a fixed horizontalplate g4 of the contour plainly shown in Figs. 8 and 9. Said plate issecured by means IOO of iillister-head stud-screws g, so as to form, l

in connection with the end surface of the stem g, a horizontal guide inwhich slides a plate or jaw g". Said jaw g is formed with a rabbet onits inner end adapted to engage the margin of an outwardly-projectingflange on the can-body and the edge of the end plate of the can-bodysuperimposed thereon and bend them dowu against the can-body to form aseam, as hereinafter more fully described. The outer end Q7 of saidjawis beveled to form a cam-surface to act against the camsurface ofaportion of the cani-ring C. A horizontal slot is formed in the bottom ofthe steml g, in which is located a spiral springvgs, said spring actingin compression between the end of the slot and a pin g, which is securedin and projects from the upper surface of the jaw-plate Q6 into theslot. The action of the spring gS on the pin g is to hold the jaw gfs inits outermost position (shown in Fig. l1) when said jaw is not incontact with the cam-ring C.

The corner-wings G' are similar to the side wings Gr in that they eachhave a stem g' and a sliding jaw gli secured between the ends of thestem g and a plate g likewise pivotally attached to the head CZ bytrunnions g engaging trunnion-sockets in the trunnion-block g2. Theeornerjaws are of the contour shown in Figs. 8 and 9 in order to enablethem to engage the cornerportions of the can-blank. They are providedeach with a horizontal arm gw, which projects inwardly through a slotformed in the head CZ to approximately the center of the head and theopening cl2, so that the inner end of the arm gm bears with its uppersurface against the lower surface of the spring-pressed plug f. Theaction of said plug on the arms is to keep the corner-wings in theposition shown in Fig. 6 when they are not in engagement with thecam-ring.

The lower end of the head d is provided with a spring-pressed sectionalpresser or heel plate I, consisting of segments 1l, having aball-and-socket connection with the head at the center, as plainly shownin Fig. 3, so as to be aorded an angular oscillatory movement thereon.Said connection is afforded by a screw K, secured on the lower surfaceof the head d, having a head consisting of a segment of a sphere andengages curvedlugs projecting upwardly from the plate-segments. Spiralsprings e" are inserted in apertures in the lower end of the head cl andbear against the upper surfaces of the plate-sections and tend to holdthe outer edges thereof down, as shown in Fig. 3. When the headisdepressed, the collapsed heel-plate I is permitted to freely enter thedepression in the end plate of the can, and when Jthe head is fullydepressed the segments of the heel-plate have swung upwardly on theirpivots and expanded, so as to force the edges of the plate outwardlyagainst the vertical flanges of the end plate, said outer edges of theheel-plate aording a backing against which the seaming-jaws act. Inorder to provide a perfect bearing-surface against the blank when thesegments z' are pressed back against the die-head d, filler-blocks i2are secured in the die-head d, so as to fill the spaces between thesegments when thrown upwardly, the outer faces of said filler-blocksbeing flush with the outer faces of the segments.

Referring now to the cam-ring C, said ring comprises a ring supported,as hereinbefore stated, by suitable lugs c c', bolted or otherwisesuitably secured to lugs ct on the frame of the press. The inner surfaceof the ring is partially formed with beveled segments forming cams c2,symmetrically disposed around the interior of the ring and adapted Theyare ,f

to engage the corner-wings G of the formerhead to move the jaws g6radially inwardly upon the depression of the head. Obviously saidcam-surfaces may be straight instead of curved, as shown. Between saidmetal camsurfaces c2 and mounted on the upper surface of the ring areblocks cs. Said blocks are secured b screws cS assin through slots in ya: o

the blocks and are afforded a lateral adjustment by means of set-screwsc4, having screwthreaded engagement with upturned lugs c5, formed on thering and bearing with their inner ends against the outer ends of saidblocks c3. Said set-screws c4 are held in adjustment by lock-nuts c6.The inner ends of each of the blocks c2 are formed with a beveled andundercut ilange c7, as plainly shown in Figs. 3, 4, 4c, and 5. Saidblocks are symmetrically disposed around the ring, so as to engage thebeveled ends gl of the slide-jaws c(i of the side wings of theforming-head to give to said jaws lateral movement toward the center ofthe press simultaneously with the vertical movement of the head d, ashereinafter more fully described.

Referring now to the die,it comprises a plate E, shaped to conform tothe figure of a bodyblank for which the press is adapted and having araised center portion e, with beveled sides e', on which the body-blankmay be set in an inverted position and centered by said beveled edgeswith respect to the die. If the can is to be seamed after it has beeniilled, the die or center block will be formed to receive the caninstead of entering the blank, as shown. Said plate E is mounted on astem e2, which has vertical sliding engagement with the carrier througha suitable guide aperture and whose lower end, when the die is under thehead and the carrier is at rest, is adapted to engage the upper end of aplunger H, mounted in the bed of the press, as shown in Fig. 3. Saidplunger H has sliding engagement at its lower end with `a sleeve 7L,which contains a spiral spring h', the lower end of which bears againsta screw-plug 7b2, inserted in the lower end of said sleeve and the upperend of which bears against the lower end of the plunger H. Said sleeveis provided with trunnions ha, which are adapted to loe engaged by the:forked arms 7c on lever K. The inner end of said lever K is raised, soas to bring the plunger I-I into engagement with the stem c2 of each dieas, the latter is brought by the carrier into cooperative position withrespect to the forming-head. Said lever K is secured at one end to ahorizontal rock-shaft K', which is rotatively mounted in suit-ablebearings on the press-frame and carries at its end remote from the leverK a rock-arm K2, which is in alinement with a slide K3, which carriesthe dog actuating the carrier B. On said slide is secured a limber pawlK4, which is adapted to engagera-nd depress the rock-arm K2 during thetime the slide K3 is retracted and `when the die is in operativeposition with respect to the form er- ICO IIO

sol

The operation of the machine as a whole .i

is as follows: Acan-blank J, having an out-- turned iianged formed onone of its margins, is placed on the die-plate E with the flange enduppermost. is inserted or laid on the top of said bodyblank J, said endplate having a depressed ,center portion to enter the upper edges of`said can-body, with its margin overlappingv and lying upon the outturnediiange of the body-blank. By the rotation of the carrier the die-plate Eis brought into register with the vformer-head. Immediately` after thismovement is effected the slide K3 is retracted and the pawl K4 engagesthe rock-arm K2, l

whereby the inner end of the lever K is raised andthe die-plate Ethereby raised to the l plane vof the cam-ring C. While said dief plateis beginning to rise the vformer-head begins to descend. When the outeredges of thespring-pressed segments of the heel-plate I are brought intoengagement with the end .plate .of the body-blank, the said plate is eX-panded outwardly against the iiange of said plate and fits tightlytherein. As the' downstroke yof the press proceeds the wingsA Gr offormer-head are ,passed down through the .cam-ring and the side jaws arethrust inwardly by lengagement of the beveled surfaces g7 on the outerends of the jaws with the beveled surfaces of the segment c7 of theAcam-blocks c3 on the ring. As the side wings are swung inwardly by thisaction of the cam- .surfaces thel inner ends of the stationary plates g4grip the opposite sides of the canblank, so as to center the blank onthe-die and lgrip the blank to-hold it in place.4 Vhile theformer-head-is descending in the manner described, the die-plate E willbe moved upwardly-to bring the upper end of the canblank approximatelyto the plane of the upper surfaces of the blocks c3, so as to -permitthe ends of the plates g4 to grip the can-body below thefiiange thereonwhen moved inwardly. When the can-blank has been so gripped by thewingsG, the die-plate is depressed in unison with the former-head to they position shown in Fig. 4, said depression being allowed bya sharpinclination in the rear end ofthe rock-arm K2, with which the pawl is atthis` time engaged, and a slight` compression-of the spring h. Thespring g8, Fig. 11, is ymade of suchstrengthas to resist compressionwhen the plates g4 of the wings G are being moved against the can-body.After .the can has beenl gripped in the manner described-thefurtherdepression ofthe head acts to move the seaming-jaws g inwardlyagainst the flanges of the end plate and canbody. The flange of the endplate comes iirst in contact with the forming-rabbet in y.beveled edgesof the blocks c3. A blank for a bottom plate side wings out after theyhave passed the At the same time the springs c11 on the posts c are inengagement with the outer ends of the arms g3 of the side wings, andsaid springs are brought under compression by the downward movement ofthe former-head. When, therefore, the jaws gG pass the cam-surfaces ofthe camblock c3, said springs act to quickly throw the side wings intothe position shown in Fig. 5. By these movements the central parts ofthe body-flange and margins of the end plate between the corners havebeen bent over and formed into a double seam. In the further descent ofthe former-head the corner-jaws are thrown forward to complete theforming of the seam. As the downward movement of the presser-headcontinues the lower outer corners of the fixed plates g4 of the wings Gencounter the beveled surfaces c2 of the cam-rin g c, as clearly shownin Fig. 6, so that the win gs are swung inwardly and the inner ends ofthe plates g4 engage the portions of the .can-body below the flange andadjacent to the corners and hold the Vblank firmly in position, as shownin Fig. 7.' As the stroke continues the forming-jaws 96 thereof arethrown inwardly by the action of the cam-surfaces on the ring-segmentsc2, so that the formingrabbets at the inner ends thereof catch themargins of the flanges in the same manner as the side forming-jawsbefore described to form the seams at the corners of the blank. It willbe understood that during the entire downward movement of theforming-head after the heel-plate thereof comes into contact with thecan-blank the die-plate moves downwardly in unison with said head. -Onthe return movement of the follower-head the'side jaws may be againthrown into contact with the seam of the blank, so as to press out anyirregularities in the seam at this point, if any exist. This may beaccomplished by raising the can-blank when the side wings are retracted,so that when the jaws gi pass the widest parts of the camblocks c3 theseam on the body will be in position to be engaged by the forming-faceof said jaws, so that said jaws will exert pressure on the seams.

It will be seen by an inspection of Figs. 8 and 9 that the acting facesof the side jaws are wider than the spaces between adjacent corner-jaws,so that said corner-jaws overlap part of the work done by the side jaws.This insures a perfect nish between the parts of the seams formed by thetwo jaws. From the Lforegoing description it will be understood that theside jaws perform their work and are IOO IIO

retracted before the corner-jaws are moved inwardly. By reason of thewidened working faces of the side jaws it becomes important that they beretracted promptly, so as not 'to be locked by engagement with thecornerjaws as the latter are moved inwardly. Itis for this purpose thatthe springs Q8 are provided, which insure a prompt retraction of thejaws. Itis for this purpose also that the springs c11 are provided,which quickly throw the side wings outwardly after they have passed thecam-blocks c3 in the descent of the followerhead.

The construction described is adapted to form what is known as a doubleseam.77 Il a single seam is to be formed, the flange on the can-body isomitted and the projecting part of the fiange on the end plate made nar-Under these conditions the formingjaws merely press the end-plate flangedownwardly and inwardly upon the can-body. In this event the parts ofthe machine are adjusted to compensate for one thickness of tinomitted-namely, the flange of the can-body.

In Figs. 1S to 22, inclusive, I have shown modified form of jaws andcam-ring for forming a double seam on body-blanks having flanges likethose shown in Fig. 23. In said figure the end plate ofthe blank J isprovided with a flange, the intermediate part of which overlies theoutturned flange ofthe body and the extreme margin j of which isdisposed ver tically and surrounds said body-flange.

In the construction shown in Figs. 1S to 22, inclusive, the corner andside jaws are each made of two relatively movable parts and the cam-ringis provided with two separate cams foractuatingeachjaw.Thecorner-jawsconsist of two plates Q11 Q15, one above the other, havingslots engaged b v guide-pins Q16, passing upwardly through the bottomplate Q11 of the wing. Q12 Q1s designate pins which pass upwardly fromthe plate Q11into'sockets in the wing and engage springs Q19 therein, asshown in dotted lines in Figs. 18 and 20. Q20 designates a like pinwhich projects upwardly from the lower plate Q15 through a slot in theplate Q1L and into a centrally-located socket in the wing and engages aspring Q21 therein. Said springs Q19 and Q2l tend to hold the plates Q11and Q15 retracted from their work. The lower plate Q15 is provided witha central shank Q22, Fig. 18, which fits in a groove in the lowersurface of the plate Q11, and the outer end of said shank and thecorresponding edges of the plate Q1*1 are beveled. The inner part of thecam-ring C is provided with a cam projection 011, adapted to engage theinclined end of the shank of the lower plate7 and the ring is providedbelow said cam projection with an inclined or cam surface 015, whichengages the inclined edge of the plate Q14. The part of the ringimmediately above the inclined surface C12 is substantially vertical,and the ring is inclined above said vertical part, as shown at G12. Theside jaws also consist each of an upper plate Q21 and a lower plate Q25,having slots engag-ed bya guide-plate Q26, similar to the guidepins Q16.Said plates of the side jaws also are placed under the influence ofsprings like the springs Q21, which tend to retract said plates. Themovements of the side and corner jaws are substantially alike and willbe described with reference to Figs. 18, 19, and 20. As the head movesdownwardly the lower plate Q1T of the wings first comes in contact withthe inclined surfaces o16 of the ring, and said wings are swung inwardlyto bring the inclined ends of the Shanks in contact with the camprojections 011. Contact of said parts in the further depression of thehead causes the wings to be moved inwardly until the plates Q17 arebrought into contact with the can-body, below the flange thereof.Further depression of the wings causes the lower plates of the jaws tomove inwardly against the compression of the spring Q12 to engage thevertical party' of the flange of the end plate and press the sameinwardly and upwardly into the position shown in Fig. 19. Immediatelythereafter the shank passes the cam projection C14 and the lower plateQ15 is thrown outwardly against the inclined or cam surface 015. In thecontinued depression of the wings the plates Q14 Q15 are moved inwardlyin unison, and the action of the two plates is substantially like thesimilar jaws of the construction previously described, the end of thedownward movement of the rings and the inner limit of movement of thejaws being shown in Fig. 20. The remainder of the operation issubstantially like that of the construction first described. It will beunderstood that the duplex side jaws are operated by inclined or camsurfaces like those just described, but located above the level of thering, as shown in the other figures of the drawings, so as to actuatethe side jaws in advance of the corner-jaws, as in saidpreviously-described construction. In practice the horizontal surfacesbetween the projec- ICO tions c11 and the surfaces 01V and the extreme lends of the Shanks Q22 are slightly rounded, and the parts will be keptwell oiled, so that the lower plates of the jaws will be forced inwardlyin the ascent of the wings sufficiently for said plates to pass saidprojection.

If the partsj of the flange shown in Fig. 23 be perfectly formed, theconstruction first described is well adapted to form the seam; but ithas been found in practice that in making a flange of this form thereistendency to the formation of an outwardly-curled bur on the edge of theflange. The construction last described insures that' the vertical partof said flange will be turned inwardly and upwardly without tendency ofthe ange being curled in the direction given thereto by the bur.

The several terms herein employed for designating the various parts ofthe machine have been employed merely for the purpose of couvenience ofdesignation and are not to be understood as limiting terms. Foriustance,the

jaws forming the parts of the seams at the corner of the can-body hereinshown-will if a can or body of other shape be operated uponbecorrespondingly changed and may not, in fact, be strictly corner-jaws.
